This roller came off an aluminum framed builders sliding unit from the early 70's. The cast housing is 5/8 wide x 1-1/8 tall and overall length is 2-3/4 without measuring screw. I am in search of two.

Thank you for posting, Adam. I recommend you look at our 81-005. This appears to be a similar match, just double check your dimensions to ensure that they match.
